摘　　要：纳米陶瓷球是一种采用控制浆料细度及粉体煅烧温度,并通过添加各种氧化物及特殊稀土材料,从而得到高强度、高耐磨性能的磨矿介质。研究从瓷球的耐磨性能出发,对比其实验室与工业应用耐磨性能的差异。实验室阶段各球径瓷球耐磨系数都在0.05g/kg·h以内,球径越大耐磨系数越低,平均耐磨系数为0.033g/kg·h,相当于钢球的1/20,氧化铝球的1/10。工业应用表明,使用瓷球作为再磨段磨矿介质与钢球相比,球耗降低了84%以上;使用瓷球作为钨矿选厂二段磨磨矿介质与钢锻相比,球耗节约为59.91%;使用瓷球作为铁矿选厂二段磨磨矿介质与钢球相比,球耗节约在87.50%以上,单位球耗基本在0.015 kg/t左右。研究表明,瓷球耐磨性能与矿石性质相关性较强,而与球磨机尺寸相关性较弱。Nanoceramic balls are a type of grinding medium with high strength and wear resistance properties,which is made by controlling the fineness and calcination temperature of powder and adding various oxides and special rare earth materials.From the perspective of wear resistance performance of nanoceramic balls,the differences of their wear resistance in laboratory and industrial applications are compared.In the laboratory phrase,the wear resistance coefficient of ceramic balls is within 0.05 g/kg·h and decreases as the ball diameter increases.The average wear resistance coefficient is 0.033 g/kg·h,equivalent to 1/20 of steel balls and 1/10 of alumina balls.In industrial applications,the use of ceramic balls as grinding media in the regrinding section reduces ball consumption by more than 84%compared with steel balls.In the second grinding stage of tungsten ore processing plant,using ceramic balls instead of steel forgings reduces ball consumption by 59.91%.In the second grinding stage of iron ore processing plant,using ceramic balls instead of steel balls reduces ball consumption by more than 87.50%with a unit ball consumption of about 0.015 kg/t.Overall,the wear resistance performance of ceramicballs is highly correlated with ore properties and weakly correlated with the size of ball mill.
